The children originally described by Susan Swedo et al. (1998) [17] usually had an abrupt onset of symptoms, including motor or vocal tics, obsessions, or compulsions. [18] [19] In addition to an obsessive–compulsive or tic disorder diagnosis, children may have other symptoms associated with exacerbations such as emotional lability, enuresis, anxiety, and deterioration in handwriting.

He is the author of the 2013 R package BioGeoBEARS, [M 18] which enables statistical comparison of probabilistic models of how the geographic ranges of species evolve on phylogenies, such as models that include or exclude founder-event speciation, [M 19] geographic distance, [M 20] or dispersal-influencing traits.
Listwise deletion will exclude these respondents from analysis. This may create a bias as participants who do divulge this information may have different characteristics than participants who do not. Multiple imputation is an alternate technique for dealing with missing data that attempts to eliminate this bias.
Note that winsorizing is not equivalent to simply excluding data, which is a simpler procedure, called trimming or truncation, but is a method of censoring data.. In a trimmed estimator, the extreme values are discarded; in a winsorized estimator, the extreme values are instead replaced by certain percentiles (the trimmed minimum and maximum).
Exclude the cardinalities of the pairwise intersections. Include the cardinalities of the triple-wise intersections. Exclude the cardinalities of the quadruple-wise intersections. Include the cardinalities of the quintuple-wise intersections. Continue, until the cardinality of the n-tuple-wise intersection is included (if n is odd) or excluded ...
[35] [36] The CANS/PANS hypotheses include different possible mechanisms underlying acute-onset neuropsychiatric conditions, but do not exclude GABHS infections as a cause in a subset of individuals. [35] [36] PANDAS, PANS and CANS are the focus of clinical and laboratory research but remain unproven. [34] [35] [36]
In statistics, Cook's distance or Cook's D is a commonly used estimate of the influence of a data point when performing a least-squares regression analysis. [1] In a practical ordinary least squares analysis, Cook's distance can be used in several ways: to indicate influential data points that are particularly worth checking for validity; or to indicate regions of the design space where it ...
Giant pandas are considered an umbrella species. Umbrella species are species selected for making conservation-related decisions, typically because protecting these species indirectly protects the many other species that make up the ecological community of its habitat (the umbrella effect). Species conservation can be subjective because it is ...
